Fast forward a few months, the touch panels really haven't gotten that much use out of them. Currently the boot image for the panel starts up linux, runs Iceweasle full screen and points to a URL on [[Pony]]. All that's left is whipping some HTML together to make a neat interface that provides information and control regarding things we currently have in the space.

The system that runs the touchpanel laptop by the door (172.30.0.31) is required for opengate-www and opengate scripts to work. It is connected by parallel port to a relay which is linked into the door buzzer system.

All the touch panel machines use PXE boot and an image from a tftp server on [[Stallion]] to run. They require network access to stallion to come up.

There are 10x [http://www.parkytowers.me.uk/thin/Wyse3150SE/index.shtml Wyse 3150SE] thin clients available to drive the touch panels. The touch panels are made by iNexio and there is a custom XInput driver available for them in the source repository.

The [[Inexio]] touch panels have their own wiki page with more info.

Symptom: mouse cursor on the touch panel is flying around without any touch input.

Resolution: Remove power to the touch panel and disconnect any USB cables, then plug the touch panel and USB cables back in.

A bunch of folks worked on getting the touch panels working. Then another bunch of folks wanted to setup some sort of crazy control Noisebridge in case of a fire thing with it, SCADA.

The system that runs the touchpanel laptop by the door (172.30.0.31) is required for opengate-www and opengate scripts to work. It is connected by parallel port to a relay which is linked into the door buzzer system.

All the touch panel machines use PXE boot and an image from a tftp server on Stallion to run. They require network access to stallion to come up.

Currently the boot image for the panel starts up linux, runs Iceweasel full screen and points to a URL on Pony. There's a neat extensible interface that provides information and control regarding things we currently have in the space.

There are 10x Wyse 3150SE thin clients available to drive the touch panels. The touch panels are made by iNexio and there is a custom XInput driver available for them in the source repository.

The netboot environment is just debian-live. If you don't read the manual you're likely to break something by accident. It's better to do development on your local machine using qemu and a copy of the config tree before executing the procedure below to push it out.

Log into stallion and make the changes you want to the files in /netboot/config as root.

sudo lh_build --force

Back up the contents of /srv/debian-live

Test your image, see the manual for how to set up a test environment. It's simpler than you think.

If everything worked, move /netboot/binary/* and /netboot/tftpboot to /srv/debian-live

Reboot one of the lesser used netboot machines and do a sanity check, make sure your changes aren't causing the machines to run out of memory and invoke the OOM killer.
